Open PGM Files

PGM stands for Portable Gray Map and it represents an image file format initially created to facilitate graphic data exchange between various platforms. Although PGM graphic files are usually stored as ASCII text format, they also feature a binary representation.

PGM image files contain header information as well as a grid of numbers representing shades of gray from black (0) to white (up to 65,536).

In order to be able to open their PGM pictures, users will need to choose and use a specialized image viewer with built-in support for this particular image format.
